When you are telling people about Islam, you will sometimes get a response like the one above. And sometimes people don't say it, but they're thinking it. That's when it's time to make the following very important point. Here's how I answered the above message:
"Yes, I get that. And I like people too. But there are some ideologies (the written ideas) that make humans do bad things. When Islamic ideas such as these are believed by Muslims, it becomes dangerous to our fellow human beings. That's just a fact. Isn't there an ideology you dislike? The KKK's? The one spelled out in Mein Kampf? It's okay to dislike an ideology, isn't it?
I often try to find an ideology my listener doesn't like, and then make that point. Usually this allows our conversation to continue, because most people agree that it's perfectly okay to dislike, discuss, and criticize an ideology. Of course. When you put it that way, people seem to understand what you're doing, and accept it.
